When county or congressional district boundaries are turned on, the map shows what county a project is located in or which Member of Congress represents the district and the percentage of the district that lies within the Great Lakes Basin. The project table "disaggregates" programs to show separate on-the-ground projects, versus showing a grant program managed by an agency or organization. For example, the map shows separate contaminated sediment cleanups implemented under the Great Lakes Legacy Act program.
The website emphasizes on-the-ground actions and does not include some projects focused on research, monitoring, public education and other broad-scale activities not focused on a specific site. The project locations may represent a specific site or the watershed in which restoration work is being conducted. In some cases the site is the
location of the lead agency. The Commission has also produced state-specific factsheets showcasing how the GLRI is benefiting each of the eight Great Lakes states.
